This paper presents a set of techniques for classification of audiosegments in a system for automatic transcription of broadcast programs. The task consists in deciding a) whether the segment is to be labeled as speech or ...

Many methods for OFDM Peak to Average Power Ratio reduction have been proposed during approximately last ten years. There are nowadays many research efforts on PAPR reduction methods with reduced computational complexity. ...

This letter deals with the basic principles and functions of the new compression standard MPEG-4 AVC, which has been developed for an effective compression of the digital video data; for digital signals of the high definition ...

This paper describes a design of the Self- Complementary Spiral Antenna (SCSA) which consists of a spiral antenna and a wideband impedance transformer. The spiral antenna and the transformer are designed separately due to ...

This paper deals with the design of two-passband bandpass and two-stopband bandreject LC ladder filters. The design method is based on the special dual frequency transformation that transforms normalized lowpass to either ...

The aim of this paper is to provide a survey of the recent development in new algorithms and techniques to solve the electrical impedance tomography (EIT) inverse problem. The EIT problem is nonlinear and ill-posed. The ...

An optimization problem for designing nonuniformly spaced, linear antenna\'s arrays is formulated and solved by means of a controlled random search algorithm. The proposed iterative method aims at a linear array and the ...

This paper deals with a dynamic range optimization procedure for active filters based on the cascade realization. Dynamic characteristics of the cascade filter depend on many factors, mainly on pole-zero pairing, section ...

The paper is focused on time domain modeling of microwave structures by the method of moments. Two alternative schemes with weighted Laguerre polynomials are presented. Thanks to their properties, these schemes are free ...
